Guyz I am looking for a nice heads and cam combo something for the street driven every day. i would like to make good numbers but i want the car to run good i dont want to spend more then $1500 on heads soo let me know what you think or what you got. And i will also be doing the other bolt ons headers lid gears exhaust . ive got about $3500-4000 to spend on performance mods the rest is for looks hood lowering kit and chip foose wheels

 

check out tsp, or search budget heads and youll find a million ideas, if search is working for you.

 

i will be building a 383 this summer and i am goin to go with the ms3 or something of that size with stage 2 ls6 heads. i am shooting for low 11s.

 

go to the sponsor sales section and vengeance has the Trick Flow as casted heads on sale for 1600 dollars they flow almost like their cnc heads. that would be your best bet for sure. they can set you up with a cam to match the heads and all that.

 

tsp has some winning combos along with vengeance racing....and you should be able to stay in your price range with no problems

 

bump......

 

talk to tsp (Texas speed) like said above they have good prices and are know their stuff. If you got all your stuff through them i am sure they would give you a discount also. Plus they would make sure all the parts work well together so your car would perform well.

 

Find someone selling a decent set of used heads on here. Due to the frequency of upgrades most ls owners go through, you can find used parts that have minimal miles and are at a great price. My h/c setup (gm mls gaskets, required gaskets for swap, timing chain, arp studs, afr heads, custom grind cam + machine shop charges) came in under 2500.00 said and done. From reading on here, talking to multiple local ls owners, the general consensus that I have gathered is that cylinder head design and porting is one of the most important pieces to a healthy performance engine, and definitely not an area where you would want to skimp if you don't have to.

For what you are looking at, I personally would do a set of ls6 heads (either from TSP, TEA, or even stock w/ port work) + associated valvetrain upgrades to accomodate cam, then look for a cam that will suit your own needs. Everyone on here has different attributes that they like/dislike when it comes to cars so everyones opinions aren't really going to help you on cam selection. Decide for yourself where you want the powerband to be, what rpm range you want peak hp and peak tq to be at, whether or not you want it audibly noticeable, and what you honestly plan to do with the car (being all motor, boosted, sprayed, etc). Take these answers and then speak with one of the sponsors that has a wide cam selection or does custom grinds and see what they can recommend you, sometimes an off-the-shelf cam won't exactly provide the characteristics you are aiming for. Also if you see an off-the-shelf that you are interested in, search on here or the other forums for dynographs of the cam so you can see the type of hp/tq curve it makes, when it makes most of its power, whether or not the cam falls off after a certain rpm (i.e. cam peaks horsepower at 5800 rpm and holds near peak for the rest of the pull or nose dives), etc. Doing so can allow you to see the characteristics of the cam and what type of manners it will have in your own vehicle, also don't just focus on peak hp/tq numbers, focus on the graph and how it makes power, peak numbers on a dyno can be drastically differing from your own due to the many variables of the dyno and other modifications that have been done.

 

i would say tsp prc 5.3 heads is what you need...

 

I agree. The "as cast 220cc" head will work great and is very close to your budget.

 

or just call TSP
